摘要： 物体在水下运动时，空化往往产生一些负面效应，导致设备剥蚀破坏、效率降低，引起剧烈的冲击振动和强烈的空化噪声。文章研究了水下超空泡的生成与保持，利用气体补充、液体喷射装置和发生器等保持超空泡的状态方式；并介绍了摩擦阻力、空气化、尾部差异化等超空泡参数，还对利用超空泡技术的水下推进控制技术做出了展望。

Abstract: When the submarine vehicle is in motion, cavitation often have some negative effects, which leading to equipment damage and erosion, reducing efficiency, causing severe vibration and intense cavitation noise. In this paper, the generation and duration of underwater supercavity is summarized. Using gas supplement, liquid injection and generator to maintain the status of supercavity is also summarized is this paper. And the paper also introduces the frictional resistance, cavitation, tail and other parameters of supercavity. The paper gives a prospect of submarine propulsion control technology based on supercavitation technology.
